To set a screen resolution for your console you can do the following log in as root

edit /etc/default/grub uncomment the GRUB_GFXMODE=640x480 and change the resolution to something you can use e.g. 1024x768

Add the line

GRUB_GFXPAYLOAD_LINUX=keep

to the file to have the same resolution at the Linux console. You do not edit the 00_header file as some suggest you need to do.
